If you control the company, then you can easily stop this by making the product manager the one who can request a UX change, not the UX team.
If you are an employee, a frontend dev, for example, then you can't change it as much as you want, other than raising it with your superiors; maybe, as an EM, you can have a
chat with the director/VP/CTO about it.
Generally, for an employee, it's more work, which is not bad; it means you are safer in your job (if it's Enterprise). Just ask them to use official ways to request a UI change, such as a Linear/Jira ticket.
